If an application doesn’t support the COM port number assigned, change the port
number in the
System Configuration Utility.
•
Check whether another application is preventing access to the port, even if it’s
not actively using it.
•
Check in the communications application that you haven’t changed the address
and interrupt for the OmniBook port.

If an I/O card stops communicating properly
•
It may have been reset if the OmniBook suspended or turned off. Exit and
restart the application, and plug in the ac adapter, if possible.
If a parallel device doesn’t work correctly
•
Its bus speed might be too slow for the OmniBook. You can decrease the
OmniBook’s bus speed by pressing FN+HYPHEN (minus). To restore the normal
speed, press FN+EQUAL (plus).
Sound Problems
If sounds aren’t audible
•
Check the playback or recording sound levels, channels, and muting. See
"Using
Sound."
•
Check the configuration of the sound card for system-resource conflicts.
•
If you’re running an MS-DOS program outside Windows and you need access to
sound and other system devices, use the special MS-DOS Mode command:
Click Start, Programs, OmniBook, MS-DOS Mode. This shuts down Windows
and loads drivers for MS-DOS. When you're done, type exit to restart Windows.
•
If you add a Zoomed Video PC card (it must be in the upper card slot), its sound
capability will not work until you activate Zoomed Video sound. While Zoomed
Video sound is turned on, normal sounds related to PC card activity are
disabled. Click Start, Programs, OmniBook, OmniBook Zoomed Video, then turn
Zoomed Video sound on or off.
If the volume keeps reverting to old settings
•
The FN-key volume and mute controls are effective for the duration of the
current audio file only. Use the Windows volume controls to make a permanent
change.
